Patented Nov. 24, 1931 UNITED STATES PATENT OFFICE Application filed February 21, 1928. Serial No. 255,926.

This invention relates to a vacuum cleaner receptacle, and has to do especially with a receptacle which consistsof arelatively cheap dirt receiving bag designed to be thrown away and a new one used in its place from time to time. o

More particularly, the invention 1s concerned with a connection between this replaceable bag, an exterior covering therefor,

10 and the vacuum machine proper. Replace able bags of the kind mentioned are usually of porous paper, and in use they are covered by an exterior member of a permanent nature.

Vacuum cleanerbags of this nature have already been proposed, and it has been proposed to provide the exterlor part, whlch is the permanent part, with a metal tubular inlet over which a tubular formation -2 in the paper bag is placed. When the entire ba assembly is placed on the machine, a. metafiic connection is elfected between the metal tubular member and a co-operating.

part on the vacuum cleaner. This has not 25 worked out in the best manner, because a dust tight joint is not always eifected, and

because considerable time and skill 1s required in making the assembly.

The present invention contemplates an un- 30 proved connection wherein a dust tight joint joint with the paper bag is positively assured.

In the accompanying drawings:

Fig. 1 is a side view of a vacuum cleaner of a type which may be used with the present invention.

Fig. 4 illustrates the position of the arts just prior to placing the inlet end 0 the paper bag over the inlet member of the main or permanent receptacle.

Fig. 5 illustrates how a. similar connection can be used with a hose for attachments for the vacuum machine.

Fig. 6 illustrates the invention when used witlh a difl'erent form of dirt receiving receptac e.

In the accompanying drawings, a vacuum cleaning machine is illustrated in Fig. 1 comprising a motor 1, an inlet end 2, and a handle 3. The draft of air set up by the motor is drawn in through the inlet end, and discharged through an outlet 4. As will be noted in Fig. 2, this outlet member tapers towards its end for the purpose of establishing a connection as will presently more clearly appear.

The dirt receiving receptacle is illustrated at 5, and this receptacle may be of rigid formation constructed of wire mesh. Such I a receptacle is described and claimed in my copending application Serial N 0. 255,925 filed February 21, 1928. Within this wire bag member is placed a replaceable dirt receiving bag 6, which may be advantageously made of porous paper. This bag is provided with an inlet end 7 which may be constructed of relatively non-stretchable paper.

The lower end head of the wire mesh bag is removable to permit insertion of the paper bag. This head being shown at 8 in Fig. 4. The head is provided with a nipple 9 which is of an elastic nature and which maybe advantageouslymade of rubber. This nipp le tapers towards its inner end as shown 1n ig. 4. The removable end head 8 may be held to the container 5 by any desirable means.

In order to place the paper bag within the i receptacle, the bag assembly is removed from the machine and the head 8 removed fromup over the nipple 9, as by means 0 tabs Y 10. The bag is then placed within the receptacle 5 and the head secured in place.

The whole assembly is now placed back on the vacuum machine and at first the parts take the position approximately as shown in Fig. 2. The nipple 9 is now pushed over the tube 4 and due to the tapered construction of the tube 4, the nipple is expanded so that a dust tight joint is efiected both between the nipple and the extension 4, and the nipple and the inlet end 7 of the replaceable paper bag.

Any desirable means can be used for attaching the bag assembly to the vacuum machine, and for this purpose the bag 5 may be provided with apertured ears 11 which fit over studs 12 carried by the machine. A suitable spring clip 13 may be utilized for snapping over one of the ears to hold the bag in place, while a hook and eye arrangement 14 may be utilized for holding the upper end of the bag assembly to the handle.

While I have elected to describe the in vention in connection with a permanent part of the bag constructed of wire mesh, it is within the invention to utilize the connection with a cloth bag. As illustrated in Fig. 6, the rear of a bag made of cloth is referenced l5, and the nipple 9 may be provided with a circumferential groove 16 in which the cloth may be secured by means of suitable wire or spring 17.

One of the features of the invention is the simple manner in which tubes for vacuum cleaner attachments may be substituted in place of a bag. Heretofore, when a metal xture was used for the bag, ametal fixture had to be used for the attachments. There was only one metal connecting member provided, usually, for the attachments and this often was misplaced. In the present invention, however, as will be noted in Fig. 5, a tube 20 for an attachment may be provided at its end with a nipple of rubber or the like, similar to the nipple 9, so that it can merely be ushed down over the extension 4: and s cient connection for the purpose is provided.
